Our Regional Educational Media Center (REMC) Association State-wide coorperative purchase organization looks at these. I know the AverMedia products do well. The larger Qomo is really good, but it is around $900. Consider a product that can be used with a microscope.
In your price range, also consider the AverMedia product. We use the AverMedia 300p at our place. Go to http://www.remcbid.org and search for document cameras or visual presenters. Also look in Selection Tools - ther eis one on visual presenters. While this service is for Michigan, you can see what we sold this past year.
